Abstract

The aim of the research was to determine the changes of S content in soil, changes in yield of wheat and content of nitrogen, phosphorus and potassium in wheat grain as a result of sulphur fertilizer application. The experiment was carried out on a calcareous chernozem soil in Zemun Polje near Belgrade, Serbia. Two forms of sulphur fertilizers were applied: elemental sulphur and gypsum. The soil and plant samples were taken after harvest. The analyses showed an increase in total and available soil S. Higher amounts of the applied sulphur caused a decline in the yield of wheat grain, and a decrease of nitrogen and phosphorus content. On the other hand, the content of sulphur and potassium in the grain was higher in the treatments where more intensive sulphur fertilization was applied.
